Make a hash of queried data(`ActiveRecord::Relation`) which user can
specify key
and value of the hash for some situations.
Example:
# Before you do it like this
authors = Author.where(name: 'Hank Moody')
authors_hash = {}
authors.each do |author|
authors_hash.store(author.id, author.desc)
end
# Now you do this
authors = Author.where(name: 'Hank Moody')
authors_hash = authors.as_hash(:id, :desc)
def as_hash(key, value, &block)
>
> k = key.to_s
>
> v = value.to_s
>
> hash = {}
>
> self.each do |item|
>
> hash.store(item[k], item[v])
>
> yield item if block_given?
>
> end
>
> hash
>
> end
>
>
is it helpful?
